New vertical shaft for the ILC experimental area on the Kitakami side

by Ricarda Laash

In our issue on 9 July, NewsLine introduced the change management process that oversees changes to the machine’s overall design. Today, we look in detail at one of the change requests that was put forward and went through: vertical shafts (as opposed to inclined tunnels) for the interaction region.

Around the World

Curious about ILC in Japan and the Higgs particle but not a physicist? Well not a problem! This little Youtube video gives answers to many questions. It is designed for school kids and will explain everything in an easy and short fashion. Also, it will introduce you to Higgs-kun - a ghost-like character representing the Higgs particle who is new at his school. So, take the time and watch this short video. You will see many interesting things!

Director's Corner

Reporting almost live from Whistler, Canada, Akira Yamamoto says progress is impressive. The conference SRF 2015 covered the latest advances in the science, technology, and applications of superconducting RF, including leading SRF accelerator projects, such as European XFEL, the European Spallation Source, FRIB, and the LCLS-II project.

From cavity studies to shaping the future of particle physics in Europe: Eckhard Elsen, scientist at the German lab DESY, will become research director at CERN when Fabiola Gianotti becomes Director-General in 2016. Elsen is well known in the linear collider community for his central role advancing not only the the performance of high-gradient superconducting cavities but also of the linear collider project itself. He is a member of and has chaired numerous committees in the world of particle physics and beyond. His term of office covers the second run of the Large Hadron Collider LHC.

一関市は、市内在住の外国語指導助手（ＡＬＴ）10人を国際化推進サポーターに登録した。ＩＬＣの北上山地（北上高地）誘致を見据え、市は国際化への提言、助言を得ようと市内のＡＬＴからサポーターを募集。(Ichinoseki city newly registered 10 internationalization promotion supporters from the city’s assistant language teachers. In view of the ILC construction around the area, city aims to collect advises and proposals.)

​ดังนั้นเราจึงเห็นได้ว่า เครื่องเร่งอนุภาคที่ใช้โปรตอนหรืออิเล็กตรอนต่างก็มีทั้งข้อดีและข้อเสียคือ โปรตอนมีมวลมากกว่าอิเล็กตรอนประมาณ 2,000 เท่า และมีโครงสร้างภายใน ดังนั้นเวลาชนกัน อนุภาคต่างๆ จะเกิดขึ้นมากมาย จนทำให้การสังเกตผลลัพธ์หลังการชนเป็นเรื่องยาก ส่วนอิเล็กตรอนเวลาถูกเร่ง จะแผ่รังสีทำให้พลังงานตก แต่การชนจะสะอาด เพราะอิเล็กตรอนไม่มีโครงสร้างภายใน (Proton or electron accelerators has both advantages and disadvantages. Protons are far more massive than electrons and has internal structure. So after observing the results is difficult. When electrons are accelerated, radiation results into energy fall. But the particle events are clean.)
